WILLIAM R. NUTTING, OF REVERE, MASSACHUSETTS.

ELECTRIC GAS-LIGHTER.

SPECIFICATION forming part of Letters Patent No. 250,279, dated November 29, 1881.

Application filed March 21, 1881.

To all whom it may concern:

Be it known that I, WILLIAM R. NUTTING, of Revere, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Electric Gas-Lighters,of which the following is a specification.

My invention relates to that class of appliances constructed to make an electric spark adjacent to a gas-burner to ignite the gas; and it consists in devices fully described hereinafter,- whereby the conducting wire or tape is prevented from being accidentally left in contact with the burner or any part of the fixture.

' In the drawings, Figure l is a view, showing a side-light gas-burner and lighting appliances constructed in accordance with my invention. Fig. 2, ation of the lighting devices; Fig. 3, a view of an electrode-support detached from the burner; Fig. 4, a viewillustrating the invention adapted to a vertically-movable burner. r

In that class of gas-fixtures in which the burner is movable, or in which one of the electrodes must be brought to the burner to make the contact and insure a spark, there is always danger of the loose suspended wire, as heretofore arranged, becoming slack, and, by contact with some part of a gas-fixture or other object, closing a circuit and running down or exhaustin g the battery. I overcome these objections by so constructing the lighting appliances that the wire is prevented from becoming slack. Different modes of effecting this may be used, according as to whether the invention is applied to a side bracket or chandelier, and according to the other circumstances of the case. Thus, with a side bracket carrying the burner A, I may use a contactpoint or electrode, D provided with a handle, E, so as to be applied by hand to the fixed electrode a on the burner, and connected to a connecting-wire, D, leading a view illustrating the oper-t (No model.)

to one pole of the battery, and s0 coiled that after being extended to bring the electrode D in contact with the electrode a it will retract and carry the movable electrode to such a position that it cannot swing into contact with the burner.

Instead of coiling the wire D it may be wound on a spring bobbin or spool, which will revolve when the electrode is drawn out, but will automatically rewind the wire when the electrode is released. Thus, with a chandelier (Fig. 4:) havinga sliding light, I, I may use a case, J, containinga coiled metallic tape,

constituting the conductor D, and combined with a spring, (like a coiled-spring tape-measure,) the electrode D being attached to the conductor, which, when drawn upon, will uncoil to accompany or permit the electrode to be carried to the burner.

To facilitate the attachment of the fixed electrode a to the burner A, I use a ring, 13, carrying the electrode, and a clamping-screw, U, or other device, whereby said ring may be secured detachably to the burner, either insulated by an intervening rim or packing of asbestus or its equivalent, or in direct contact with the burner, according to the character of the lighting apparatus.

I claim- In an electric gas-1i ghting apparatus, aburner and fixed electrode, combined with a movable electrode arranged above the burner, and an extensible conductor, substantially as set forth.

In testimony whereofI have signed my name to this specification in the presence of two subscribing witnesses.

WILLIAM R. NUTTING.
